I know all that, but probably didn't express it very clearly. I'm just
trying to decide whether the 4-5k to install roll steering is worth the
expense.


Pilots here in Europe are wondering the same thing, since roll
steering is being mandated for PRNAV.

I wouldn't pay 4-5k USD for it, personally, not even here because
there is no mandatory PRNAV airspace.

However, if the USA goes the way Europe has, and starts bringing in
lots of RNAV SIDs/STARs, then you will need roll steering because
these are supposed to be flyable hands-off, AIUI.

Roll steering will become important, if not essential, when RF legs
become common on advanced RNAV instrument approach procedures. The
procedures themselves will be in limited numbers, so they will be easily
avoided. But, some of them will provide access that a TF to TF leg IAP
can't.
